Date of Observation: 02/01/2021
Name: Zach Guy
Zone: Northwest Mountains
Location: Irwin Upper Upper Westwall
Avalanches: Nothing new since the slides reported yesterday.
Weather: High thin clouds increased in thickness through the day. Mild temps. Light winds.
Snowpack: Explosive testing on upper elevation west-facing terrain with relatively minimal snow safety work this season. No results. Probing revealed discontinuous and isolated persistent slab structures across the terrain, due to previous wind erosion. Anything with a hint of south had a thin, melt freeze crust on the surface after yesterday’s warmup. Crusts did not soften today. Measured 1.6” Storm SWE in a relatively sheltered near treeline slope.
